METHOD AND APPARATUS FOR CONTROLLING DEPTH OF PENETRATION OF LIGHT ENERGY USING ULTRASOUND ENERGY

摘要

An apparatus for controlling a depth of penetration of light energy using ultrasound energy, according to the present invention, comprises: a light source for generating light energy; and an ultrasound (US) transducer configured to generate an air bubble using ultrasonic waves in a region in which the light energy proceeds to increase a depth by which the light energy penetrates an illuminated subject. The apparatus generates an air bubble by adjusting the intensity of ultrasound energy within a range in which the ultrasonic waves cause no damage on tissues, thereby increasing the depth of light penetration.
